InputConnectionCompat

public static final int INPUT_CONTENT_GRANT_READ_URI_PERMISSION = 1

When this flag is used, the editor will be able to request temporary access permissions to the content URI contained in the InputContentInfoCompat object, in a similar manner that has been recommended in Sharing Files.

Make sure that the content provider owning the Uri sets the grantUriPermissions attribute in its manifest or included the <grant-uri-permissions> tag.

Supported only on API >= 25.

On API <= 24 devices, IME developers need to ensure that the content URI is accessible only from the target application, for example, by generating a URL with a unique name that others cannot guess. IME developers can also rely on the following information of the target application to do additional access checks in their ContentProvider.

• On API >= 23 packageName is guaranteed to not be spoofed, which can later be compared with getCallingPackage in the ContentProvider.
• getUid is guaranteed to not be spoofed, which can later be compared with getCallingUid in the ContentProvider.

public static boolean commitContent(
    @NonNull InputConnection inputConnection,
    @NonNull EditorInfo editorInfo,
    @NonNull InputContentInfoCompat inputContentInfo,
    int flags,
    @Nullable Bundle opts
)

Calls commitContent API, in a backwards compatible fashion.

public static @NonNull InputConnection createWrapper(
    @NonNull InputConnection inputConnection,
    @NonNull EditorInfo editorInfo,
    @NonNull InputConnectionCompat.OnCommitContentListener onCommitContentListener
)

Creates a wrapper InputConnection object from an existing InputConnection and OnCommitContentListener that can be returned to the system.

By returning the wrapper object to the IME, the editor can be notified by onCommitContent when the IME calls commitContent and the corresponding Framework API that is available on API >= 25.

public static @NonNull InputConnection createWrapper(
    @NonNull View view,
    @NonNull InputConnection inputConnection,
    @NonNull EditorInfo editorInfo
)

Creates a wrapper InputConnection that implements InputConnection's features on past versions of Android.

Currently, handles commitContent by dispatching to performReceiveContent, enabling apps to use setOnReceiveContentListener to specify handling for content insertion from the IME.

Usage:

public class MyWidget extends View {
    @Override
    public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
        InputConnection ic = super.onCreateInputConnection(outAttrs);
        if (ic == null) {
            return ic;
        }
        String[] mimeTypes = ViewCompat.getOnReceiveContentMimeTypes(this);
        if (mimeTypes != null) {
            EditorInfoCompat.setContentMimeTypes(outAttrs, mimeTypes);
            ic = InputConnectionCompat.createWrapper(this, ic, outAttrs);
        }
        return ic;
    }
}
